Abstract

The aim of the study is to determine the effect of rudder area and speed on a ferry ship maneuvering performance, especially during the turning circle and zigzag maneuver.  MATLAB-simulink was used to simulate turning circle and zigzag maneuver. The simulation utilized model based on the concept of Mathematical Modelling Group (MMG) includes testing/separating components of the hull equations, propeller and rudder as well as the interaction among them (hull, propeller and rudder). The result of simulation indicated that rudder  dimension and ship speed  affect both turning circle and zigzag maneuver of the ferry reasonably.

Abstract

Kota Batam merupakan daerah dengan julukan kota industri. Sejak setelah bertranformasi menjadi kawasan industri kota Batam memiliki berbagai macam indutri yang dibangun, sehingga terbuka banyak peluang kerja yang tersedia. Salah satu keberlanjutan yang perlu didukung yaitu ketersediaan tenaga kerja terampil yang memiliki kompetensi dibidang keteknikan. Gambar dan penggunaan software CAD menjadi salah satu kompetensi yang perlu dipenuhi oleh masyarakat. Upaya menyediakan tenaga kerja terampil dapat dilihat dari tersedianya sekolah menengah kejuruan. Meskipun demikian, keterbatasan fasilitas praktik menjadi salah satu kendala yang dihadapi sebagian sekolah dalam melaksanakan layanan pendidikannya. Kegiatan Pelatihan Penggunaan Software AutoCAD kepada siswa/i SMK Kota Batam Tahun 2024 kemudian hadir menjadi salah satu solusi untuk dapat membantu sekolah dalam meningkat mutu pendidikan vokasi di Kota Batam. Pelatihan ini didanai secara internal oleh Politeknik Negeri Batam dan telah dilaksanakan di Politeknik Negeri Batam pada 23 – 26 Juli 2024. Adapun mitra peserta pengabdian ini adalah dari siswa dan guru SMK S Aljabar Batam, SMK S Kartini, SMK N 9 Batam. Beberapa luaran yang telah diselesaikan pada kegiatan pengabdian ini adalah terselenggaranya kegiatan dan penyusunan modul pelatihan. pemberitaan pada media masa, HKI modul, poster dan video kegiatan.

Abstract

Tools such as jigs are becoming important in the production process. Jigs are often used in the cutting or shaping process in the form of making workpieces in production. However, ever-changing variations in demand can lead to changes in jig efficiency. Therefore, modifications are necessary to maintain accuracy and meet the demands of diverse markets. This research was carried out by modifying the design of the slider jig on the width of the rail slider which was enlarged from before and adding support to the clamping plate which aims to improve the accuracy and effectiveness in the drilling process. To find out the results of the difference before and after the modification of the slider jig, a test was carried out by conducting a visual inspection of the profile point hook that had been ground using a profile projector with a scale of 10 :1 which showed that the results of this modification were included in the value of the drawing tolerance value and in accordance with the specifications in the company and based on data taken from PT. XYZ in the engine working time of 3 hours and 3 minutes, a total output of 164 pcs was found out of the total target of 158 pcs. This resulted in a productivity percentage of 103.80%. This shows that this jig modification is effective when used.
